DERAILIN Specification of Letters Fatent.

G DEVICE,

Patented Dec. 24, 1907.

'T 0 all whom it may concern.

Be it known that we, WILLIA OWEN CLEGG and OSCAR J AMES ASMANN, citizensof the United States, residing at Palestme, 1n

the county of Anderson and State of Texas,

have invented certain new and useful Improvements in Derailing Devices,of which the following is a specification.

My invention relates to railway appliances and has special reference toapparatus for preventing collisons and particularly to that class ofapparatus commonly termed derailing devices.

The chief objects of my invention are to provide a sim le derailingdevice that can be readily instal ed at any location desired; to furnishan eflicient means for derailing a car or engine that can be easily seenby the engineer or other train men thus affording an additionalsafeguard; and to produce a strong, durable and easily operatedapparatus for the purpose sought.

1 accomplish the above objects by the use of the device illustrated inthe accompanying drawing which forms a part of this specification, andin which:

Figure 1 is a plan View of a portion of a railway track equipped with myimproved derailing block the latter being in operative position Fig. 2is'an end view of the same; Fig. 3 is a view similar to Fig. 1 but withthe derailing block in its inoperative position, and Fig. 4 is aperspective view of the derailing block; Fig. 4 is a plan view of amodifled construction of the derail block and operating mechanism.

Referring to the drawing in detail, the numeral 5indicates themain-rails of a railroad track and 6 the supporting ties, upon which issecured a bed plate 7 adjacent to one of the main rails. A rectangularplate 8 preferably of malleable cast iron, is provided with a heavy,downwardly projecting marginal flange 9, its inner face adjacent to themain rail being furnished with a groove 10 corresponding in contour tothe rail head against which it lies when the plate is in operativeposition. The upper face 11 of the plate is inclined downward from theouter margin and the anterior edge 12 is beveled to form a wedge uponwhich the flange of the car wheel will easily climb when brought incontact therewith. Extending diagonally from the forward inner corner tothe outer rear corner of said plate 1s a vertlcal flange 13 cast lnte- Igral with the plate. A short piece of rail 14 is spiked down upon theties along the inner side of the main rail upon which the plate 8 rests,to form a firm support for the portion of the plate which projects overthe said main rail. An arm 15 cast integral with the flange 9,

and extending at a right angle therefrom, is

furnished with a slot 16 which is engaged by a pivot bolt 17 fixed inthe bed plate 7. Ad-

j acent to said arm 15 is installed an ordinary switch stand 18, boltedto the bed plate 7 and provided with a shaft 19 the lower end 20 ofwhich is bent'at a right angle with said shaft and then upwardly to forma crank the vertical portion 21 being received in a hole 21 formed inthe extreme end of said arm 15 and having a turning fit therein. T o thesaid shaft is attached the usual operating handle 22 which is adapted tobe locked in sector notches in the top plate of the switch stand in theordinary manner.

In Fig. 4 is shown a modification in the form of the derailing block andoperating mechanism which will permit trains to pass safely in onedirection while the block is in position to derail one approaching fromthe other way. This is accomplished by placing a split switch springbetween the derail block and the switch stand. The latter is located ata sufficient distance from the main track to allow the introduction of arod 22, which is pivoted at one end to the crank arm 21 and then passesloosely through brackets 23 which are fixed to a flat bar 24. Theopposite end of the rod is supplied with a fork 25 which has pivotalconnection with the arm 15 by means of a bolt 26. Upon the rod 22 issecured a collar 27, and loosely mounted on the same rod is a washer 28and between the said collar and washer is located a heavy spring 29which surrounds the said rod and is limited in its extension by a nut 30which has threaded engagement with the rod. This arrangement will permitthe lateral movement of the derail block with reference to the maintrack when suflicient force is applied to compress the spring 29.

The method of using my improved derailing block is as follows: Theapparatus having been located at the desired point along the main track,the switch is turned to the position shown in Fig. 3 with the crank 20extending parallel with the main track rails, in which position thederailing block will be swung clear of the track and can in no Wayinterfere with the passing trains. When it is necessary to set thedevice in its operative position so that no train can pass in thedirection for which the apparatus is set, the crank 20 is swung throughan arc of 90 degrees by means of the handle 22. This movement will throwthe blockinto the position shown in Fig. 1 In this position the flangeof the car wheel, the latter being shown in dotted outline in Figs. 1and 2, will impinge upon the inclined edge 12 and will readily mount theincline and coming in contact With the flange 13 will be unavoidablydeflected to the outer side with the result that the companion wheelwill be dragged from its rail. Should by any chance the first wheel becarried over the deflecting flange and still keep its rail, it would bea physical impossibility for a succession of wheel flanges to ride oversuch a decided obstruction without becoming dislodged from the track.The flange 13 being made sufliciently heavy and the strong flange 9bearing against the outside of the main rail and being locked beneaththe rail head it will be practically impossible to dislodge the devicetowards the median line of the track even with the impact of a heavyengine proceeding at a high rate of speed.

In the modified form of derail block shown in Fig. 4 the part 31 (Fig.4)is omitted, so that a wheel traveling in the direction of the arrow 32will strike the flange 13 and thrust the block clear of the rail bycompressing the spring 29, the reaction of the latter causing the blockto resume its initial position.

It is obvious that certain details of con struction of the devices of myinvention as herein disclosed may be departed from with- Out affectingthe spirit and scope of my invention and I do not wish, therefore, to belimited to the precise construction set forth.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is

1. In a derailing device, the combination with a rail of a railway line,of a plate provided with a wheel deflecting flange, a depending flangeinterlocking with said rail, a slotted arm formed integral with saidplate, a pivot engaging the slot in said arm, and operative meansconnected with said arm for moving the plate.

2. A derailing device, including a rail of a railway, a movable plate, adeflecting flange formed integral with said plate, a depending flangeadapted to interlock with the lateral surface of said rail, a slottedarm for the plate, a pivot engaging said slotted arm, and a switchoperatively connected with said arm.

3. A derailing device, including a rail of a railway line, a bedlate, amovable plate having a deflecting ange and a depending flange adapted tointerlock with the lateral surface of said rail, an auxiliary rail forsupporting said movable plate when in its operative position, an armformed integral with said plate and provided with a slot, a pivot boltsecured to the base plate and engaging said slot, a switchstand securedto the bed plate adjacent to said movable plate and operative connectionbetween the switch and the said arm.

In testimony whereof we aflix our signatures in the presence of twowitnesses.
